Tomcat 8.5.X: Migrate Valve javacode from Tomcat 7

Question

I need to migrate one of our custom Valve code from Tomcat 7 to Tomcat 8.5:

import java.io.IOException;



import javax.servlet.ServletException;

import javax.servlet.http.HttpSession;



import org.apache.catalina.Container;

import org.apache.catalina.Manager;

import org.apache.catalina.Session;

import org.apache.catalina.connector.Request;

import org.apache.catalina.connector.Response;

import org.apache.catalina.valves.ValveBase;



public class SessionManagerValve extends ValveBase {



    @Override

    public void invoke(Request request, Response response) throws IOException, ServletException {

      // ...

    }



    public HttpSession findSession(String id, boolean updateLastAccessTime) {

        try {

            Container container = getContainer();



            // works with Tomcat 7.x, but not with Tomcat 8.5 anymore...

            Manager man = container.getManager();



            Session sess = man.findSession(id);

            return sess.getSession();

       } catch (Exception e) {

           return null;

       } 

    }

}

The

Container

interface does not provide the

getManager()

method anymore. According to the Tomcat migration guide, accessing the

Manager

has moved from

Container

to

Context

.

Can anybody give me a hint how to access the

Manager

from within the

ValveBase

object?

Thanks in advance,
Rainer

EDIT: The Context configuration is - as correctly noted in the answer -

<Context path="" ...>

    <Valve className="SessionManagerValve" />

</Context>

Answer 1

Assuming your Valve is at the Context level (it would have to be for the code above to work) then you need:

((Context) getContainer()).getManager();
